TOKYO -- Smaller companies play a big role in Japan's electric vehicle battery supply chain, indirectly supporting the likes of Toyota Motor and Tesla. But many are struggling to keep pace with the speed and scale of investment needed as EV demand booms, threatening to create bottlenecks in an industry that Tokyo is keen to promote.
"We recently received requests from Europe, the U.S., China and South Korea -- including two major automobile companies -- to buy our machines, but we turned them all down," the president of a Japanese machine maker told Nikkei Asia. "There's just no room in our production capacity right now."
